# Gruner’s 1930 English Canon Book I prints venesection and depletion as therapy

Date: 1930

## The fact

In 1930 O. Cameron Gruner issued A Treatise on the Canon of Medicine of [Avicenna](/people/avicenna), an English presentation of Book I now scanned on Internet Archive. The dated public instrument is that book. It prints humoral crisis, evacuation, and venesection as ordinary therapy. Avicenna did not typeset 1930 London. The row stores the English depletion heading, not a 1025 autograph bleed list.

## Context

Latin faculties had already taught evacuation for centuries. Gruner made the same heading readable without Latin. Later bedside harm from routine bleeding is a reception path with lag; this catalog does not invent a death tally. Split any observational case-writing onto an improving row.

Avicenna is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

## Evidence and sources

The named official or archival page and the independent publisher independently describe this instrument.

Official or archival record: Gruner, A Treatise on the Canon of Medicine of Avicenna (1930) — scan (https://archive.org/details/AvicennasCanonOfMedicine; Internet Archive).

## Significance

Printed venesection-as-therapy is a health-capacity harm heading: depletion can be taught as care. High confidence on the 1930 text, medium on any one later clinic.

## What is established and what is not

Established as a dated public record of this instrument.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.
